"When the average person pictures a healthy soil in their mind, they probably have an image of a loose, dark-colored soil that is somewhat moist and filled with earthworms. Just Google “healthy soil” and you’ll be presented with countless photos of people holding that exact thing. Many people associate earthworms with soil health, and for good reason. Earthworms are beneficial for soil aeration, water infiltration, thatch control, nutrient recycling and they can increase microbial activity. They are truly movers and shakers when it comes to soils.
There are over 7,000 different species of earthworms which are divided into more than 700 genera and 23 families (Edwards, 2021). Only a small fraction of that total is native to North America. Most of the earthworms that dominate our soils here in the U.S. were introduced from Europe and Asia. Lumbricus rubellus, the red earthworm, is a familiar sight in many American gardens, but it’s actually an earthworm from Europe that was most likely introduced via soil from early settlers."
